Please help me in resoving the issues I'm facing with Toad. I'm using Toad ver. 126.96.36.199 for Oracle 10g on Windows 7 Professional. Oracle 10g and Toad both are installed on same machine. My problem is that after startup of Toad when I try to establish a connection to the oracle it gives me the error Can't initialize OCI. Error -1 I did some googleing to resolve this issue and tried following solution 1. Added ocidll=C:\oracle\product\10.2.0\db_1\BIN\oraclient10.dll parameter to startup, in the shortcut of the Toad. 2. Added ocidll=C:\oracle\product\10.2.0\db_1\BIN\oci.dll parameter to startup, in the shortcut of the Toad. I tried with both the options mentioned above seperately, but that couldn't help. Can sombody please help me to resolve this issue. Thanks in Advance.
